Eaton convincing in terms of safety, performance and operational availability. Passive arc protection Safety Management for xEnergy control cabinets Switching to safety. Short circuits in electrical systems can develop a huge destructive impact and endanger human life. This applies in particular to short circuits which cause an arc. Electric fault arcs produce a faulty connection between system parts with different potentials. In doing so, enormous amounts of energy are released into the environment, primarily as heat and radiation energy of very high intensity. To effectively prevent personal and material damage in the event of a short circuit, Eaton has developed a comprehensive package for passive arc protection in xEnergy control cabinets. Technical data xEnergy control cabinets Tested according to IEC/TR 61641 Rated frequency 50/60Hz Permitted unaffected current under arc conditions Iparc 65kA Permitted arc burning time tarc 300ms Nominal voltage Ue 415V Rated insulation voltage Ui 1000V Contamination level 3 Protection type IP40 Internal separation Form 4 Building construction requirements The concept of personal protection in control cabinets is based on the fact that the pressure generated by hot gases, which are formed during an arc in the control cabinet, can escape upwards from the enclosure. Therefore, it is imperative to pay attention that sufficient ceiling height and/or other building-related superstructures are available above the control cabinet to ensure a...
